treme simplicity and one that may be economically manufactured.

The manner in which the above and other objects are elfectuated will bereadily apparent from a reading of the specification taken'in connectionwith the accompanying drawing, in which:

Figure 1 is a top plan view of the dolly in its operative position;

bumper l l thereon. To the bumper is attached a dolly [2 which isarranged to receive a draw-bar $3 of a trailer M.

The dolly frame is preferably made of channel iron and consists of aU-shaped member l5 which has attached thereto the diagonal crosssupports 56 and H, the supports forming an X and being reinforcedagainst lateral tension by the bar l8.

Where the members [6 and I! cross, there is provided a reinforcing platel9 which also acts as a support and attaching means for the ball 20. Theelements I 9 and may be made integralor separate.

To the transverse portion 2 I' of the dolly is attached the means bywhich'the dolly is connected to the bumper l l and while, in thedrawing, only two of such means are illustrated, it should be understoodthat any number may be employed. This attaching means is very simple ofdesign and application and consists of a removable plate 25, which isclamped over the bumper H to the plate 26, by means of the bolts 21 and28.

On the plate 26 is a forked standard 29 which holds a member 39 by meansof the bolt 3|. The joint thus formed will permit up and down motionbetween the dolly and the tow car and as the forward end of draw-bar l3fits over the ball by which the front end of the trailer is supported.The swiveling action of the wheels will permit them to easily follow thedirection of the tow car.

In order to compensate for roughness in the roadway I provide springs 36and 31 on each of the wheels 34 and 35. The spring-s are positionedbetween a movable arm 38 and a stationary arm 39. The vertical action ofthe front of the trailer is thereby minimized and cushion d.

While I have illustrated and described the preferred form of theinvention, it should be understood that various changes may be madewithin the scope of the appended claim.

What I claim is:

In combination with a trailer vehicle and a draft vehicle, a dolly forconnecting the trailer and draft vehicles and for supporting the forwardend of the former, said dolly including a substantially U-shaped,rearwardly opening frame, wheels supporting the dolly and swivellyconnected to the rearwardly extending ends of the frame, theintermediate portion of the frame being disposed transversely thereofand being provided with forwardly projecting bracket arms, clampsdetachably connected to the rear bumper of the draft vehicle and eachhaving a rearwardly projecting bracket arm pivotally connected to one ofsaid forwardly projecting bracket arms, crossed braces connecting therearwardly extending ends of the frame, a brace connecting theintermediate frame portion to the crossed portions of the cross braces,and a reinforcing plate secured to said crossed portions of the firstmentioned braces and having an upstanding coupling element forengagement with the trailer vehicle.
